摘要： Techniques for selectively translating resource requests from a program running on a computer system are disclosed. The resource request may be a request to access a file, library file, API, etc. The resource request may be a system call or library call. The computer program may be non-native to the computer system. Translation of resource requests may occur within the operating system or outside it. A resource request containing a reference to a first path and file name may be selectively translated by altering the resource request to contain a reference to a second path and file name. After selectively translating a request, he request is caused to be serviced. A resource request may be serviced by forwarding it to an operating system, and a result may be sent back to the program.
摘要翻译：公开了用于从计算机系统上运行的程序选择性地翻译资源请求的技术。资源请求可以是访问文件，库文件，API等的请求。资源请求可以是系统调用或库调用。该计算机程序可能是非本机的计算机系统。资源请求的翻译可能发生在操作系统内或其外部。可以通过改变资源请求来包含对第二路径和文件名的引用来选择性地转换包含对第一路径和文件名的引用的资源请求。在选择性地翻译请求之后，他请求被提供服务。可以通过将资源请求转发到操作系统来服务资源请求，并且可以将结果发送回该程序。

摘要： A method for executing non-native binaries on a host computer architecture comprises receiving the guest executable binary into a computer readable medium. The guest executable binary is executed on the host computer architecture by translating the guest executable binary into a translated executable binary. Each instruction of the translated executed binary is then executed on the host computer architecture. Signals are responded to by placing signal information on a signal queue and deferring signal handling until a safe point is reached. A computer system implementing the method is also provided.

摘要： A method for executing non-native binaries on a host computer architecture comprises receiving a guest executable binary encoded on a computer readable medium. The guest executable binary is executable on a first computer architecture. Moreover, the guest executable binary includes a mutex lock encoded instructions for implementing a mutex lock. The guest executable binary is then executed on the host computer architecture by first translating the guest executable binary to a translated executable binary. The encoded instructions for implementing a mutex lock are translated by mapping the mutex lock to an instance of a compound mutex lock data structure. A computer system implementing methods for executing non-native binaries on a host computer architecture is also provided.
